"Ihv strips 3 4 out) M supply of water entering the apparatus is small then the regulating-valve is adjusted that the discharge will be proportionate to the supply, so that the channels will be filled with Water to their full ca )acity, and the electrically-charged strips wi l have their surfaces fully covered to more effectively treatthe water assing between them.

Fig. 4 s ows my electrolytic apparatus in full operation as placed on a filter. I do .not confine myself to the use of any special type of filter, and show the combination of my improved apparatus with a filter to explain how simply t ey coact with each other without any material alteration being requiredin the filter. The receptacle 7 is connected with any source of electric supply-as, for instance, a battery 21 or dynamo. A lamp 22 or any suitable resistance can be put in the circuit 23 to reduce the voltage or amperageof the current. When the switch or lamp IS turned ofi, the electric current in the apparatus is disconnected. I find in practice that'it is well to first crmit the treated water to ass through inen, bolting-cloth, or other fa Me 24, so as to strain any dead matter or other ingredients .which have been rendered harmless or which may have coagulatcd. The strained Water will then pass downward through any strata 25 26, and thereby supports 26, provided for filtration into a compartment 27 below the filtering means, from which it may be drawn by a faucet 28, as

.usual. r

Fig. 5 shows a duplex system of treati water electrically on a larger scale, one tan being shown in section and the other one in side elevation. The arrangements of the metallic strips 8 4 and connections are substantially as hcrcinbc'fore described, exce )t that the body 31 32 33 is made of wood. Ti water is regulated by cocks at the inlet 29 and outlet 30. The strips forming the spiral channels may be of tinned ironorothcr metal, being less expensive than aluminium. The

electrical connections which when thecnrrent is turned on converts the metal strl s into anodes and cathodes are arranged in t 1.- same manner as in the apparatus used for domestic purposes.

Suchbeing the constnrction of my imcvroved apparatus, the o )cl'fltiml is as follows: hen water is passed I own through the filling and hollow projection 10, it enters the l outer convolution of the spiral channel, taking the course indicated by arrows in Fig. l. The sides of the channel being formed (it netalhc strips which are respectively energized i by negative and )ositive electrical currents, any mineral or ot ier matter contained in the i water capable of being electrically allot-ted i is treated in the circuitous path that-the wai ter is compelled to take. The water having 1 reached the ccnterof the apparatus, it is compolled to enter and pass along a second channel until it finds an outlet through the checkvalve 13 below the apparatus. The friction of the water against the sides of the channel sets u a rotaryniotion, whereby the water is brought in closer and better contact with the anodes an'd cathodes than where a larger body of water is treated in a straight chamber or in a chamber not having the su efficial area of the spiral channels which cm- )loy. The battery being removed or distant irom the apparatus, the treated water is not subjected to the fumes or gases arising from the battery, as is the case where the battery forms part of and is contained within an electrolytic waterpurifying apparatus. By changing the electric wires at the poles the current maybe reversed ora reversing-switch 34 of ordinary construction can be placed somewhere in the circuit for this purpose.

When it is desired to repair or clean the apparatus, the cap is removed, the electrical connections are unfastened, and the bolts unscrewed from the nuts. The cover is lifted from the body, and the metallic strips can be removed an new ones instantly inserted without the use of any tools. The cover is replaced, the electrical connections are made, the cap is fastened to the cover, and the apparatus is ready for operation again.

In the tanks shown in Fig. 5 the abovedescri )tion l'dr replacing.1netallic channels is modified, there being no cap to removal Such being the description of my tion, what I claim as new is 1. In an' apparatus for electrically treating water, a separable body or casing with inlet and outlet openings, the opposite heads or walls of said body portionbeing formed of insulating material and having 0 positely-arranged grooves, plates orstrips o electricallyconduetive material removably seated cdgewise in said grooves, whereby when the body or casing is separated, the plates may be removed, and means for crmducting an electric current to the plates or strips, substantially as described.

2. .111 an apparatus for electrically treating water, a casing provided with a body portion, an insulating-cover, a plurality of spirally-arranged metallic strips or plates secured between the lower part of the casing and the insaluting-cover, the inner terminals of said spiral metallic plates or strips bcim arranged near the center of thc rcccptaclh and th supplying electric current to said plates or strips; substantially as described.

in an apparatus for purifying water clcrtricnlly, a recept aelo having inlet andout' lot openings, -a plurality of spiral lliillllllt',

lll| r-; or plates forming channels phrallol to cash other, tho moor Lr-rnnnals of which are near the mentor of the rereptai'lc and ad acent each other, means for admitting Water into I 5 insulating material, spiral grooves 1n the upthe outer COHVOlllllUlli of onc of the channols,

' the water passing through said rhannvls in a rotary movement toward the center whore it caters aseeondary channel in a reverse direc- Lion, flowing toward the periphery of Lho re i oxtcnding to the center thereof, and an elecreptaclc, through the outlet-opening, and

nwans for supplving electric current to the 1 plan-s or strips; sulistantiallv as described.

4. in a \vator-puril' ing apparatus, the

combination with a hollow cusmg having a removable wall, said removable wall and the wall opposite the same being formed of insulating material with oppositolyplaccd grooves therein, metallic plates or strips with their edges resting in said grooves, and means, for conducting an elm-trio curroni to the plates or strips; substantially dcscribed.

5, in an apparatus for electrically treating water, aseparahle body as described, each component part being provided respectively wvith an inlet and an outlet opening, and having a plurality of spiral grooves on its inner surface, said grooves being opposite to and on i a line with each other when the parts of sold hod are placed together, in combination with a plurality of coiled metallic strips adapted to be seated edgewise in the said grooves, and means for electrically connect.- ing said strips with opposite oles of a sourcc of electric supply, substantia ly as described.

6. In combination with a filter, a lid therefor comprising a hollow sepai a hle bod) ofinsulating matcriil, an hill-t and outlet to said body, said bod being adapted to receive waiter undvr pressure and carry it to the: llltor, a pair of substantially parallcl metal strips forming two coils mounted in said body in such a planner asjo form two channcls, and moans carried by opposite ends of said strips in connect said strips to an electrical supply.

7, In an a )paratus for the purpose described, a hollow separable hodycomposed of poi and lower interior sides of said body, a pair of spiral metallic coils fittin in said grooves and havin r their outer an s secured in the sides of the ody and their inner ends trical connecting means connectcdto said. coils.

8. In an apparatus for the purpose described, a hollow separable body composed of insulat ng material, spiral grooves in the upper and lower interior sides of said body, a

; pair of spiral metallic coils fitting in said grooves and havmitheir outer ends secured in the sides of the ody and their inner ends extending to the center thereof, said coils being so arranged as to allow water to flow in one direction toward the center and then revcrse and allow it to flow toward the outer side without traversing the same channel more than once, an inlet to one channel, an outlet to the other channel, and an electrical source having its positive and negative connected, rcs actively, to the coils.
